X-Particles: Preview Explosia in Octane

Recommended Posts

Howdy. I'm trying to preview an explosion made from Explosia in Octane's Live Viewer and am having difficulties. 

 

My understanding is that in order to preview an explosion in Octane, you must:

  1. Create a xpCache Object.
  2. Change xpCache Object EFX Format to "OpenVDB" under it's attributes. 
  3. Choose "Build Cache," within xpCache object's attributes.  
  4. Create "Vdb Volume" object under Octane Live Viewer > Objects.
  5. Select Vdb Volume object, set end frame > first frame > "digits," to 6 (because, according to tutorial guy, that is what X-Particles uses). 
  6. With Vdb Volume object still selected, under it's attributes choose file > browse to first exported .vdb file in the exported sequence.  

 

What it is supposed to look like:

Mine is empty, though:

If it helps, I made a video doing this procedure:

 

Any ideas on how to make this explosion property display in the Octane Live Viewer? 

 

Thanks!

Hey man!

 

I hope you're well - have you discovered a solution? I have a very similar issue, but instead, when I import the VDB volume, the fist frame appears in my Octane Live Viewer, and as soon as I change the Start and End values (from 1 to 120 like my amount of cached frames), I have a message "VDB:
Not found!" and my volume disappears from Live Viewer.

No idea what could be causing that!

 

Thanks for your time!

Okay, I found out what I was doing wrong - super rookie mistake, I haven't set the Digits to 6 in my VDB Volume window!
